I was out of town for 2 months but forgot to tell my friend to take care of the pool while he was house sitting. I tested the water and the ph was a little low but I've fixed that. When I went to clean the filter it was blue which is the first time this has happened. The filter does have pvc pipes connected to copper pipes coming out of the ground. There was also a thin film on top of the water that is clear but when it collects near the pump it's a bluish color similar to the filter. I brought a sample to the local pool store and everything tested fine. There's no algae, the water looks clear and the plaster seems fine. So is the blue stuff on the filter and the thin film on top of the water the result of the copper and the low ph? I've cleaned the filter twice and the film on top of the water is gone but the filters are still blue. I took pictures of filter but don't have pictures of the film. Is the pool safe to swim or do I have to drain? Thanks for any advice
blue because of copper?

About the blue film, it was like dust and pollen that sometimes sits on top of the water: it's mostly clear, but when around the pump it sometimes collects and becomes a grayish color
Safe to swim now even if the filter turns blue? Or should I keep cleaning out the filter until it's no longer blue since ph is 7.4 right now? Or do I have to drain the pool?
If you have the pH at 7.4 then it should be safe. Those filters are probably stained and will never be white again.
